Question

name a species which can act both as conjugate acid and conjugate base​

Answer 1

H2S gas is which can act as both conjugate acid as well as conjugate base.

Answer 2

Answer:

Water is a specie which can act both as a conjugate acid and a conjugate base.

Explanation:

• The oxygen atom in the water molecule possesses two lone pairs, one of which might be utilised to create a connection with an H+, allowing it to behave as a base in a process.
• Water is amphoteric because according to the observations it has the ability to function as both an acid and a base.
• Water is amphoteric in nature, by saying that we mean that it can act as both an acid and a base.
• As a result, it is capable of performing all four functions: conjugate acid, conjugate base, acid, and base.

Water as conjugate acid :

• Water behaves as a base when it interacts with an acid.
• The hydronium ion, H3O+, is the conjugate acid of water, generated by the interaction of a hydrogen ion with a water molecule.

Water as conjugate base :

• Water's conjugate base is the hydrogen ion.
• Water behaves as a base when it interacts with an acid: The hydronium ion, H3O+, is the conjugate acid of water, generated by the interaction of a hydrogen ion with a water molecule.
